Are there still sea monsters yet to be discovered?

A movie that really captured me as a kid was James Cameron's The Abyss. The idea that there are things beyond imagination right here in our own oceans is fascninating, because maybe? I hear it over and over: "we know more about the surface of the moon than our own oceans".

Another thing I hear is "well if it's there, we would've found it by now." This is somewhat discouraging to all of us still holding out hope that great wonders still exist beneath the sea. But then I read stories like this, about the discovery of a new species of fish at great depths, and my hope is renewed ever so slightly.

What do you think? Are there still sea monsters out there yet to be discovered?

Oh, absolutely there are more monsters to discover! No doubt about it.

The ocean is so vast and so deep, and we've barely even explored the first hundred feet or so under the surface. I'm sure there are incredible things there still waiting to be seen. It's always seemed weird to me that in the last century we've invested vast amounts of time and money in space exploration but comparatively little in ocean exploration, and the ocean is far more accessible to us (and far more important to our survival) than, for example, the far reaches of the solar system.

On a related note, it's 2018 and The Abyss still isn't available to buy in HD! The best version you can buy is an awful non-anamorphic DVD release that's almost twenty years old and was considered poor quality even when it first came out in 2000. James Cameron has been promising a 4K Blu-ray release for years, but still nothing. 😢

I'm getting off-topic but I can't help but note that True Lies suffers from the same problem. Come on James Cameron I want to buy all of these!

I appreciate the enthusiasm! I hope you're right. One thing I struggle with is the desire to witness these discoveries in my lifetime while knowing that making these discoveries likely endangers the future of whatever it is that's being discovered. I wonder if it's better these unknown creatures / ecosystems remain unknown.

Giant Squid had been rumored to exist for centuries because dead Giant Squid body parts were washing onto shore. It wasn't until 2013 that the first live Giant Squid was seen by humans and captured on camera.

Also, in this century a bacteria was found that gets its energy from photosynthesis off the dim light of hydrothermal vents deep in the ocean where the sun's photons cannot reach. No one expected to find this, nor does it live in our science books. It shook biologists' understanding of what's possible on our own planet. It makes me wonder what else we'll find.
